Two people were on board, but neither was injured. There was some damage to the aircraft and antenna array.

The runway was closed for two hours while the scene was cleared, causing some delays. The runway is operating normally now.

The aircraft, a Beechcraft Baron, was doing training exercises related to a simulated takeoff or simulated engine failure.
